MOP-HEAD.

Specification of Letters Patent.

Patented Dec. 31, 1907.

. To all whom 'it may concern:

Be it known that I, HAROLD M. STUReEoN, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Mop-Heads; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompany,

ingdrawings, and to the letters of reference marked thereon, formingpart of this specification.

My invention relates to the construction of mop-heads, and the object ofmy improvement is to simplify the construction of mopheads and renderthem more effective in operation.

My improvement is illustrated in the accompanymg drawings in which:

Figure 1 is a top or plan view of a mophead embodying my invention. Fig.2 is a side view of the same with the lever thrown forward. Fi 3 is across section of the same on the Tine acx in Fig. 1. Fig. 4 is aperspective view of the spring of my improved mop-head spring showingthe studring upon the upper end thereof. 1

The drawings show a mop-head, the general features of which are ofsimilar construction. It consists of a head A provided with a centralsleeve or socket A which receives and is secured to the end of a handleD. The head A is provided with a groove a which extends along its outerface and across the ends a thereof to receive a wire yoke C. The handleD is reduced in size from the end of the sleeve A for sufficientdistance to receive a spiral spring E having a ring E formed on itsupper end, which spring extends from the sleeve A to the ring E on its uper end, and when relaxed forces said ring E against the shoulder (1formed by the enlarged portion of the handle D, as illustrated in Fig.2.

Upon the upper end of the-spring E, I form a ring E by winding the coilsof wire snugly together so that there is absolutely no torsion or sprintherein at that point. This ring E may lie formed of as many coils ofwire as may be desired,but I preferably use three coils. On oppositesides of the ring E I form studs e 6, preferably by making shortoutwardly projecting return bends in one of the coils of wire formingsaid ring E. These studs 6 e may however be formed in any way desired,but I prefer to use the construction herein shown.

After the ring E and studs 6 e thereon have been formed as described, Ipreferably treat the spring E and ring E and studs 0 e to a tin bathwhereby the several coils of the spring E become securely soldered andoined together at 0 so that they form one integral ring with oppositelyprojecting studs 6 e thereon. I may, however, use the spring E With itsring E and studs 6 6 Without tinning the same with good results, but Iprefer to tin the sprin with its ring as it not only joins the severacoils of the ring E securely together, but also preserves the spring andring from rust. The great advantage of a spring having a stud-ring uponits upper end integral therewith is its cheapness of construction, thefacility with which the same may be assembled with the other parts ofthe mop-head, and also that a stud-ring so conconstructed upon the upperend of a spring is better adapted to exert a straight line pressure fromboth studs e 6 upon the spring E.

The arms 0 C of the yoke C are bent inward so as to engage and bepivoted in the holes f in the lever F. This lever F is made of the usualsemi-circular form in cross section, so that it fits down over thehandle D, and when in this position the holes f therein engaging thestuds e e on the ring E of the spring E are on the plane of the centerof the handle D, which insures the lever remaining in a locked positionuntil released by the operator.

I am aware that mop-head levers substantially like the lever F have beenpivoted on studs on a cast ring resting against the upper end of thespring, and that mop-head evers have been pivoted to one of the coils ofthe spring itself; but I am not aware that a ring as ever been formed ofthe coils of the wire wound closely together integral with the springitself and having studs formed thereon as I have herein shown anddescribed.

Therefore having described my invention so as 'to enable others toconstruct and use pressed loops projectin from one of the coils the sameWhat I claim as new desire to secure of said ring, substantial y as setforth. 10 by Letters-Patent of the United States is: In testimonywhereof I affix my signa- In a spiral mop-spring, a spirally Wound ture,in presence of two Witnesses. 5 spring, an integral ring on one endthereof HAROLD M.
